Good stuff when using the trio
Great stuff. Never lets me down. Don't forget the grow and bloom bottles. Maybe some calmag. Silica is great too. Love General Hydroponics.

Plants Love General Hydroponics...I asked them
This is a simple review because...General Hydroponics knows how to make great nutes. My latest plant is growing "too" big! It's healthy and has absolutely no signs of any problems. Beautiful deep green leaves - even the old ones. But, this is only 1 of 3 nutes used together for any grow. If you think you can buy better for less, or simply settle for less, you'll always have less than optimal plants. I'm in my third grow with General Hydroponics and will never use anything else. It's simple to mix, lasts in the bottles for darn near ever (I left them sit for more than 2 years and then used them and they worked just as if they were new), and well worth the price. The last week before harvest, you simply use only water - no nutes - and the plants are clean. Maybe General Hydroponics should have developed the Covid vaccine!

This is the only nutrient I would buy by the Gallon
Definitely the MVP of the FLora Series trio. This is the best nutrient for plants in the vegetative state and the high Nitrogen combined with all of the micro nutrients is an quick fix all 90% of all yellowing plants. It has practically all of the essential micro nutrients and enough Calcium in it so you don’t have to use cal mag. You still need magnesium though so epsom salt or flora bloom works wonders. Trace elements include: Iron Boron Cobalt Copper Manganese Zinc molybdenum Pair this with Flora Bloom and you basically do not need anything else (F bloom has phosphorus, potassium and magnesium)
